' This invention relates to new and useful nnprovements 1n railway rolling stock and more particularly to the hem/kingsv whlch transfer a portion ofthe load from the ve-' hicle underiiraine -to the'truokusuch as is shown and described in an application filed April 4, 1925, hearing fieriel .Number 20,832, of which this is e division...

The principal object of the invention is to provide a se v cent-e1 "or aligning caring that will, by virtue or its structure, not to align the vehicle body and the'trucl: wheelsl Another object is to provideimesns for maintaining proper relationship of the parts inell possible working positions.

A still further ob ect is to provide means -tor lubricating certain surfaces Where there IS frictional contact.

view, the invention consists in certain novel features oi? construction andarrangement oi? pert-s, heieinaftermore fully described and cleiinech' and illustrated in the accompanying; drawings, in which-s M y Figure 1: is partly 2L side elevetion' an d partly e sectional viewelongthe line 1-1 of Figure 3.'

'The top surface 5 of the rocker ,sezitbeering is slightly concave transverselyof the truck frame and "isprovided with upstzinding sides 6. The

rocker seat 7 rests on the" rocker seat hearing 3 and is provlded wlthen undersurmce slightlyconvex to correspond to thetop sur face 5 of the rocker seat bearing. Depend- 111g lips 8 extend over the ends of the rocker see-t hearmp; to prevent d splacement;

' Two parallel grooves or sockets 9 are 'equirhstently spaced from theeenter. of: the top The rocker 10 supports the bearing plate 13, the under surface of which comprises two parts loeud- 16, each of which slopes upwardly toward the center. Downwardly rest e ces-ronerron, or GRANITE airy, rumors, I

.ings 12 are provided in the top surfece of the rocker on ielther side 1 of the center.

depending lugs 14! are spaced from the center of bearing plate 13. adopted to pass.through-the openings 12' inthe rocker and. help to nieinta-ii'i the propi er relation between the parts.

In ll possible operating pOSllLlOllS-Of the rocker assembly, etleest one of the lugs e1:-

These lugs tends into 1 its opening 12 in T the rocker.

'lhis insures the proper errengement ofthe parts and since my rocker assembliesere' customarily used'in pairs, it maintains each individual rocker inproper' positionirelzrtive to its companion.

It is preferable in centering means to arrange the rocker-end its correletedfymrts so thet the plane of the rocker movement is ,tangent'to an ere struck from the pivot point of the truck. How ever, it is feasible toineke the: entire beerthe adaptation of the ing conform .to'the are of the curve struck from the pivot point, in which cese the' parts, instead of being" formed in straight jtiieees as shown in the drawings, would be curved. Itwould' elsobe possible to make each half of the besring'essembly tangent to this are. i v

The beuring'plete 13 acts as a load sup portii'ig member and is carried by the -vehicle underframe to transfer a portion of the weight of the vehicle to the truck through the. medium of the rocker bearing and while in the present disclosure plate 13- all) rocker on said bearings;
